Here are some pictures as requested.

I hope they are of use - I've just done some general ones at the moment - if you need more drop me a line in the next few weeks from this post (after that time I'm sorry to say they'll be off down the tip).

For clarity these have come off of my European 1981 W123 300D. It has no ABS - but I don't know if that makes a difference...

The pictures are made as though the car has been turned upside down - imagine the car sitting on its roof and you can look down onto the fuel and brake lines.

The three lines are spread apart in an attempt at clarity!
